Final answer:

The destination host will typically drop an incorrect frame, as standard network protocols like TCP/IP use error-detection mechanisms that, upon detection of corrupted data, lead to the discarding of the frame without further action.

Step-by-step explanation:

If the destination host receives a frame that is incorrect, it will typically drop the frame. In many network protocols, including TCP/IP, the integrity of data is checked using error-detection techniques like checksums or cyclic redundancy checks (CRC). When the destination device detects an error, such as a mismatch in these checks, it concludes that the frame is corrupted.

The standard action for the destination device is then to silently discard the frame without taking any further action. However, in some protocols or configurations, the destination may send an error message back to the source to indicate that the transmitted data was corrupted and request retransmission, commonly known as an ACK or NACK signal.

But this behavior is part of a higher layer protocol, not the frame handling at the data link layer. Simple frame handling upon error detection as the question seems to ask will result in the frame being dropped.

Option 2) Send an error message to the source host, 3) Forward the frame to the next hop, and 4) Correct the frame and forward it to the destination are incorrect actions for a frame received in error at the destination host in most standard network protocols.
